To serve the 397B-parameter Qwen 3.5 Mixture-of-Experts (MoE) model on Ironwood TPUs, engineers developed a modular JAX/Pallas optimization stack that achieved up to a 4.7x inference speedup for prefill-heavy workloads. The team bypassed severe hardware sharding constraints by deploying a hybrid Data Parallelism and Expert Parallelism (DP+EP) topology, paired with custom low-level communication fusions like a hierarchical reduce-scatter to optimize cross-device token routing. Finally, by executing hardware-aware custom kernels—such as Batched Ragged Page Attention and a fully-fused Gated DeltaNet (GDN) block—they successfully saturated HBM bandwidth and TensorCore MXUs to push system throughput near its theoretical roofline limits.

The Metropolitan Museum of Art unveils two new generative AI initiatives with Google Arts & Culture.

Users can now edit and revise their email drafts in Gmail via the prompt bar, using custom refine instructions in Help me write. Previously the refines were limited to preset options like Polish, Formalize, and Shorten. Now if your first draft isn’t quite perfect, you can provide a precise follow-up prompt in your own words to further refine it, and even undo or redo any edits you make.

Whether you need to add a missing detail to the second line or include a deadline for your request, simply type the instruction and Gmail will instantly update the draft for you.

Getting started

• Admins: This feature is available by default if both Gemini for Workspace in Gmail is enabled and Workspace Intelligence access to Gmail is enabled.
• End users: This feature is available by default. Visit the Help Center article to learn more about drafting emails with Gemini in Gmail.

Rollout pace

• Rapid Release and Scheduled Release domains: Rolling out now, with expected completion by July 20, 2026

Availability

• Business: Business Starter, Standard, and Plus
• Enterprise: Enterprise Starter, Standard, and Plus
• Consumer: Google AI Plus, Pro, and Ultra
• Other Editions: Frontline Plus
• Education Add-ons: Google AI Pro for Education
• Other Add-ons: AI Expanded Access

Google Images is turning 25. Here’s a look back at some major milestones — and new ways to explore and create visual content.

Google will both invest in and purchase energy and storage from Steel River Energy Center in Mississippi County, Arkansas.

Maintaining an enterprise-grade video conferencing environment requires visibility into the health of its devices. We're introducing new ways to see Google Meet hardware user-reported feedback directly in the Admin console.

We’ve also updated user-side feedback options to replace generic reporting with structured actionable feedback making it easier and more intuitive for room participants to report problems.

Redesigned user interface

The new feedback menu on Google Meet hardware now features responses that are tailored to the reporting context (In-Call, Out of Call, Live stream). These new feedback options collect better details, making it easier for admins to understand and troubleshoot the issue.

In-Call Feedback: Users are presented with call specific options to report a problem , like “Can’t see others” or “Poor audio or video quality.”

Out-of-Call Feedback: When filing feedback from the touchscreen landing page, users now see a new set of join-related problems, including “Can’t join Meet call” and “Can’t join Teams call.”

Livestream Feedback: Users viewing large-scale livestreams will see dedicated options to report a problem.

Admin console improvements

The Google Meet hardware section of the Admin console now features enhanced monitoring tools. Feedback is no longer proxied as a background telemetry event; it is now a primary, sortable “device information” column within the device list.

Enhancements include two new columns on the device list page, including:

• Last feedback submitted - A sortable column displaying the exact timestamp of a device’s most recent report, which can be filtered by 1, 3, 7, or 30 days. Clicking the timestamp opens a side panel containing specific feedback details.
• Feedback in the last 28 days - A cumulative count of reports filed for a specific device over a rolling 28-day period, allowing for the identification of recurring faulty devices.

Admins can get more information about a specific “Last feedback” by clicking on the date, a side panel will open providing the specific feedback details:

In addition, we’re introducing a new "With feedback in last 7 days" filter, which instantly prioritizes devices with recent reports and repositions the feedback columns to sit next to the device name for immediate visibility.

A new filter to glance at devices with feedback filed in the last 7 days.

Getting started

• Admins: Ensure the “Let users send feedback to Google” checkbox is selected in GMH Settings > Data Sharing > Feedback is ON  at the domain or organizational unit (OU) where the device is enrolled. Visit the Help Center to learn more.
• End users: Users can report feedback during or after a call or livestream via the “Report a problem” button. Visit the Help Center to learn more.

Rollout pace

• Rapid Release and Scheduled Release domains: Gradual rollout (up to 15 days for feature visibility)  starting on July 14, 2026

Availability

• Available to all Google Workspace customers with Google Meet hardware devices
